With CVRCalc, I worked with two infusion nursing clinicians to help turn their research into a utility for iPhone and iPad. Designed to help clinicians working in vascular access and infusion nursing choose and monitor the correct catheter to vessel ratio. The model is based on the 1st Place poster awarded at the Association for Vascular Access 2017 Scientific Meeting in Phoenix and supported with this publication.


Find CVR

Using the vessel diameter and catheter size, clinicians can get a simple red, yellow or green rating to illustrate the ideal catheter to vessel ratio.


Calculate Vessel Diameter

Using the catheter size and CVR ratio, clinicians determine the area consumed within the intravascular space


Get Catheter Suggestions

Using vessel size and the target CVR, CVRCalc can make suggestions on catheter size based on widely-used catheters avaiable on the market.
